Abstract

The study was conducted with the objective of developing a pest management scheme in vegetables that is compatible with the principles of IPM. The first stage of the study was the mapping of the arthropod population profile in the two crops under study (stringbeans and eggplant). Eight insect pests were recorded on stringbeans with five criticial windows. In eggplant, leafhopper, thrips, and fruit and shoot borer predominated and five critical windows were also observed. The profile was used as the basis for identifying critical stages when the crops were most susceptible to pest damage and in formulating corrective measures or pest management intervention. The second stage was a field comparison of farmers' pest management practices with strategically timed insecticide applications. Field trial results in the two vegetable crops showed that strategic insecticide applications outperformed farmers' practice by producing higher yields, requiring fewer sprays, lowering production cost, and incurring higher profits or ROI. The strategy optimized the effect of insecticides on the pests while minimizing the impact on beneficial arthropods. Further studies are presently being conducted which include insecticide x parasitoid complementation. Initial trials showed promising results.
